For the related next strcpy(), the destination length is less than 512,
but the source maximize length may be 'OPROMMAXPARAM' (4096) which is
more than 512.
One work flow may:
openprom_sunos_ioctl() -> if (cmd == OPROMSETOPT)
getstrings() -> will alloc buffer with size 'OPROMMAXPARAM'.
opromsetopt() -> devide the buffer into 'var' and 'value'
of_set_property() -> pass
prom_setprop() -> pass
ldom_set_var()
And do not mind the additional 4 alignment buffer increasing, since
'sizeof(pkt) - sizeof(pkt.header)' is 4 alignment at least.

Commit 384816051c (SUNRPC: fix races on
PipeFS MOUNT notifications) introduces a regression when we call
rpc_setup_pipedir() with RPCSEC_GSS as the auth flavour.
By calling rpcauth_create() while holding the sn->pipefs_sb_lock, we
end up deadlocking in gss_pipes_dentries_create_net().
Fix is to register the client and release the mutex before calling
rpcauth_create().

Intel Smart Connect is an Intel-specific ACPI interface for configuring
devices to wake up at regular intervals so they can pull down mail or other
internet updates, and then go to sleep again. If a user enables this in
Windows and then reboots into Linux, the device may wake up if it's put to
sleep. Since there's no Linux userland support for any of this, the machine
will then remain awake until something else puts it back to sleep.
I haven't figured out all that much about how this works (there's a bunch
of different ACPI calls available on the device), but this seems to be
enough to turn it off. We can add more features to this driver if anyone
ever cares about figuring out what the rest of the calls do or writing some
Linux userspace to implement the rest of it.

Intel Rapid Start Technology is a firmware-based suspend-to-disk
implementation. Once placed in S3, the device will wake once either a
timeout elapses or the battery reaches a critical level. It will then resume
to the firmware and copy the contents of RAM to a specialised partition, and
then power off the machine. If the user turns the machine back on the
firmware will copy the contents of the partition back to RAM and then resume
from S3 as normal.
This driver provides an interface for configuring the wakeup events and
timeout. It still requires firmware support and an appropriate suspend
partition.

Commit 8f898e92ae removed the redundant
reads of bInterfaceProtocol from the descriptors, but introduced a
regression to devices with quirks of type QUIRK_AUDIO_FIXED_ENDPOINT,
since fp->protocol is not set in setup process.
As a consequence, audio streams would not get initialized, as the
following logs show:
[ 48.923043] setting usb interface 3:1
[ 48.923056] Creating new capture data endpoint #81
[ 48.923484] 4:3:1: cannot set freq 48000 to ep 0x81
This patch sets fp->protocol in create_fixed_stream_quirk() and
resolves the regression.

XFS removes sgid bits of subdirectories under a directory containing a default
acl.
When a default acl is set, it implies xfs to call xfs_setattr_nonsize() in its
code path. Such function is shared among mkdir and chmod system calls, and
does some checks unneeded by mkdir (calling inode_change_ok()). Such checks
remove sgid bit from the inode after it has been granted.
With this patch, we extend the meaning of XFS_ATTR_NOACL flag to avoid these
checks when acls are being inherited (thanks hch).
Also, xfs_setattr_mode, doesn't need to re-check for group id and capabilities
permissions, this only implies in another try to remove sgid bit from the
directories. Such check is already done either on inode_change_ok() or
xfs_setattr_nonsize().
Changelog:
V2: Extends the meaning of XFS_ATTR_NOACL instead of wrap the tests into another
function
V3: Remove S_ISDIR check in xfs_setattr_nonsize() from the patch

drm/i915: Workaround incoherence with fence updates on Valleyview
Jon Bloomfield came up with a plausible explanation and cheap fix
(drm/i915: Fix incoherence with fence updates on Sandybridge+) for the
race condition, so lets run with it.
This is a candidate for stable as the old workaround incurs a
significant cost (calling wbinvd on all CPUs before performing the
register write) for some workloads as noted by Carsten Emde.

This hopefully fixes the root cause behind the workaround added in
commit 25ff1195f8
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date: Thu Apr 4 21:31:03 2013 +0100
drm/i915: Workaround incoherence between fences and LLC across multiple CPUs
Thanks to further investigation by Jon Bloomfield, he realised that
the 64-bit register might be broken up by the hardware into two 32-bit
writes (a problem we have encountered elsewhere). This non-atomicity
would then cause an issue where a second thread would see an
intermediate register state (new high dword, old low dword), and this
register would randomly be used in preference to its own thread register.
This would cause the second thread to read from and write into a fairly
random tiled location. Breaking the operation into 3 explicit 32-bit
updates (first disable the fence, poke the upper bits, then poke the lower
bits and enable) ensures that, given proper serialisation between the
32-bit register write and the memory transfer, that the fence value is
always consistent.
Armed with this knowledge, we can explain how the previous workaround
work. The key to the corruption is that a second thread sees an
erroneous fence register that conflicts and overrides its own. By
serialising the fence update across all CPUs, we have a small window
where no GTT access is occurring and so hide the potential corruption.
This also leads to the conclusion that the earlier workaround was
incomplete.
v2: Be overly paranoid about the order in which fence updates become
visible to the GPU to make really sure that we turn the fence off before
doing the update, and then only switch the fence on afterwards.

Daniel noticed a problem where is we wrote to an object with ring A in
the middle of a very long running batch, then executed a quick batch on
ring B before a batch that reads from the same object, its obj->ring would
now point to ring B, but its last_write_seqno would be still relative to
ring A. This would allow for the user to read from the object before the
GPU had completed the write, as set_domain would only check that ring B
had passed the last_write_seqno.
To fix this simply (and inelegantly), we bump the last_write_seqno when
switching rings so that the last_write_seqno is always relative to the
current obj->ring.
This fixes igt/tests/gem_write_read_ring_switch.
